A 280 N force is pulling an 80.0 kg refrigerator across a horizontal surface. The force acts at an angle of 18.0° above the surface. The coefficient of kinetic friction is 0.200, and the refrigerator moves a distance of 8.00 m.
break up the pulling force into vertical and horizontal components.
When determining friction force, remember the vertical component of pulling force subtracts from weigh to determine the normal force.
